Offensive head coaches want to tinker with the offense or even run it altogether. There's just too much complexity in NFL schemes these days for me to think that someone that is running his own offense is also as effective as a head coach.

The guys that pull it off like Payton have a quarterback that is so versed in the offense that he becomes a de facto OC.

A guy like Chip Kelly is going to want his paws all over that offense and is going to be a mad tinkerer. I just don't like it.

I want my coach to instill toughness, discipline and attitude in his players. Those are traits more commonly found in defensive coaches/players. The swagger from a football team generally builds through its defense.

You absolutely need a good offense to win these days, but I think you get that from a qualified, creative OC working under an organized, focused HC.
